10. OPERATION
(Continued)
10.2.1 Setting of Internal Function (continued)
(5) Switch of external setting voltage range: F5
When using this function, the F4 must be set to “1” to switch to “auto” mode.
※
F5:OFF: default factory setting, the external supply voltage range of 0V to 15V.
※
F5:ON: function number "5" is set to "ON", the external supply voltage range of 0V to 10V.
●
The relationship between external current/voltage command and output current/voltage is
shown in the figures below. The welding current and welding voltage corresponding to
welding conditions setting voltage may differ from the indications in the graphs due to wire
stick-out length or dragging of output cable. These graphs are only for reference.
Ext. voltage 1: externally supplied command voltage within 0–15 V. (at shipment setting)
Ext. voltage 2: externally supplied command voltage within 0–10 V with F5 set to “ON”.
(6) Setting of up-slope time: F6
Up-slope time is the time for increasing welding conditions stepwise when initial current is
changed to main current. The factory setting for upslope time is 0 second, and it can be
adjusted by F6 with a setting range 0–10 seconds.
This function is used when wire burns up while conditions are switched over due to the large
difference between initial current and main welding current settings.
(7) Setting of down-slope time: F7
Down-slope time refers to the time period from main welding current (down) to crater current
gradually. The factory setting for down-slope time is 0 second, and it can be adjusted by using
F7 with a setting range 0–10 seconds.
For example, use this function when bundling wire or other phenomena occur during the
transition due to the relatively large difference between the setting value for welding current
and that for crater current.
